Objective: The purpose of this study was to report the effect of traditional Korean medicine (TKM) in alleviating the side effects of lung cancer patient undergoing immunotherapy. Method: A 43-year-old man, who was diagnosed with non-small cell lung cancer, received pembrolizumab treatments. The patient was treated with acupuncture and herbal medicine (Geoeoyangpye-tang) to control various uncomfortable symptoms. The degree of pain was measured by the numeric rating scale (NRS). The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core 30 (EORTC QLQ-C30) and the EORTC 13-item lung cancer-specific module (EORTC LC-13 questionnaire) were used to assess the change in the quality of life. Results: After the TKM treatment, the flank pain and arthralgia based on the NRS were significantly improved. Various uncomfortable symptoms such as fatigue, dyspnea, insomnia, and loss of appetite were also significantly improved, based on the EORTC QLQ-C30 and EORTC QLQ-LC13. The size of the primary tumor was decreased during treatment. The disease status was stable radiologically after two months from discharge.

Frost heave is one of the representative engineering characteristics in cold regions. In South Korea, which is located in seasonal frost area, structural damage caused by frost heave and thaw happens and the need for research on the frost heave is increasing. In this paper, newly developed transparent temperature-controllable cell is used to focus on the frost heave. Frost susceptible artificial soil is used to analyze water intake rate which is one of the important factors in frost susceptibility criteria. Frost heave rate and water intake rate have similar behavior after heave by freezing of pore water converges. O-ring installed in the upper pedestal to measure water intake rate generates side friction between the inner wall of the freezing cell and O-ring, thereby hindering frost heave. Therefore, the frost susceptibility criteria using the water intake rate is not reliable. It is appropriate to use frost heave rate which has similar behavior with water intake rate. Frost heave tests were performed under two different specimen heights. Overburden pressure, temperature gradient and dry unit weight were set under similar state. Based on laboratory testing results, frost heave is independent on the specimen height.

Hwangryunhaedok-tang (HT) is prescribed in oriental medicine to treat inflammation-related diseases. This study examined the anti-bacterial effect to select the index components of Traditional Chinese Medicine (TCM) HT. The disc diffusion method and minimum inhibition concentrations (MIC) tests were conducted to measure the antibacterial activity of HT. The strains were Staphylococcus aureus ATCC 25923 and Escherichia coli 23724. Berberine and geniposide were selected as the index components of HT and were analyzed quantitatively by high-performance liquid chromatography (HPLC). As a result, the inhibition ring was formed at $11.7{\pm}1.3mm$ and $8.7{\pm}0.7mm$ at HT 20 mg and 10 mg on S.aureus ATCC 25923, respectively; and $8.0{\pm}0.0mm$ at HT 20 mg on E.coli ATCC 23724. The MIC were 31.25 mg/mL in S.aureus ATCC 25923 and 125.0 mg/mL in E.coli ATCC 23724. In quantitative analysis for standardization, HT contained 16.55 mg/g of berberine and 81.85 mg/g of geniposide. Overall, when antibiotics are developed using natural products, they may reduce the side effects and inhibit resistant bacteria. If research on HT continuously proceeds, positive developments are expected to be made in oriental medicine as well as in various other industries.

This study investigated the effect of extracorporeal shock wave therapy on the knee angle, MAS, and TUG of the affected side in patients with hemiplegic strokes. This study selected 20 patients who received rehabilitation treatment at a hospital after having been diagnosed with stroke. The control group (n=10) received the general physiotherapy (proprioceptive neuromuscular facilitation), and the experimental group (n=10) applied the extracorporeal shock wave therapy (ESWT) to the injured limb after PNF treatment. This study used an integrated kinematics analyzer (4D-MT, Relive, Korea) to analyze walking, timed up and go test to evaluate the dynamic balance ability of patients, and MAS to evaluate the spasticity. In the study results, knee angle were significantly different in all groups(p<0.05) but there was no significant difference between the groups(p>0.05). In the study results, TUG were significantly different in all groups(p<0.05) but there was no significant difference between the groups(p>0.05). Based on the results of this study, I hope that more detailed research will proceed.

Cardiovascular disease (CVD) and its complications are the leading cause of morbidity and mortality in the world. Because of the side effects and incomplete recovery from current therapy, stem cell therapy emerges as a potential therapy for CVD treatment, and endothelial progenitor cell (EPC) is one of the key stem cells used for therapeutic applications. The effect of this therapy required the expansion of EPC function. To enhance the EPC activation, proliferation, and angiogenesis using dronedarone hydrochloride (DH) is the purpose of this study. DH received approval for atrial fibrillation treatment and its cardiovascular protective effects were already reported. In this study, DH significantly increased EPC proliferation, tube formation, migration, and maintained EPCs surface marker expression. In addition, DH treatment up-regulated the phosphorylation of AKT and reduced the reactive oxygen species production. In summary, the cell priming by DH considerably improved the functional activity of EPCs, and the use of which might be a novel strategy for CVD treatment.

Blocking electromagnetic waves on the exterior walls of buildings effectively reduces the intensity of electromagnetic fields in buildings, which leads to attenuation of electromagnetic disturbances, so there is a great interest in developing technologies. In this study, SiC by-products and graphite generated in the semiconductor field were selected and mixed into mortar after pretreatment such as pulverization to evaluate their physical properties and electromagnetic wave shielding performance. Considering the economic efficiency of each shielding material, only 10% volume of the outermost side of the experiment was mixed with each shielding material to evaluate the shielding performance. The shielding performance was predicted when the experiment was manufactured by mixing the shielding material with the entire volume of the experiment using the shielding effect evaluation formula. The results of the experiment showed that the shielding performance was up to 20 dB when SiC grains were mixed with shielding materials, the shielding performance was up to 18 dB when graphite powder was mixed with shielding materials, and the shielding performance was up to 28 dB when SiC powder was mixed with shielding materials, and the shielding performance was close to 30 dB, which is known to have a shielding rate of 99.9%.

We studied the effects of the extract of aerial parts of hydroponically cultured ginseng (HGE) on alcohol-induced liver damage (AILD) in mice. AILD was induced by the oral administration of ethanol (EtOH) (25%; 5 g/kg body weight) for seven days in the study as well as EtOH-only groups. However, HGE (4 and 12 mg/kg) was orally administered (once daily for ten consecutive days) only to the study group, three days prior to the EtOH treatment. The HGE-treated group showed significantly lower levels of alanine aminotransferase and aspartate aminotransferase than the EtOH-only group. In addition, HGE administration decreased the level of serum lactate dehydrogenase, a known marker of liver damage. The effect of HGE on AILD was found to be dose dependent, and the consecutive administration of HGE showed no side effects in mice. Our study indicates that HGE treatment can potentially reduce oxidative stress and toxicity in the liver of alcohol-treated mice and that HGE can be a useful therapeutic agent for alcohol-induced hepatotoxicity. Additionally, a simple and efficient high-performance liquid chromatography-ultraviolet detection method was developed for determining the contents of four major ginsenosides in HGE. The aerial parts of hydroponically cultured ginseng were extracted using 70% fermented ethanol, and the contents of ginsenosides F5, F3, F1, and F2 in HGE were found to be 2.5, 4.4, 1.4, and 23.3 mg/g, respectively.

Phenylketonuria is the most prevalent disorder caused by an inborn error in aminoacid metabolism. It results from mutations in the phenylalanine hydroxylase (PAH) gene. If untreated or late treated, results in profound and irreversible mental disability. Newborn screening test identify patients with phenylketouria. The early initiation of a phenylalanine restricted diet very soon prevents most of the neuropsychiatric complications. However, the diet therapy is difficult to maintain and compliance is poor, especially in adolescents and adulthood. Since 2015, American Medical College of Medical Genetics and Genomics (ACMG) recommended more strong restrictive diet therapy for target blood level of phenylalanine (<360 umol/L). For over four decades the only treatment was a very restrictive low phenylalanine diet. This changed in 2007 with the approval of cofactor therapy (Tetrahydrobiopterin, BH4) which is effective in up to 30% of patients. Data from controlled clinical trials with sapropterin dihydrochloride indicate a similar occurrence of all-cause adverse events with this treatment and placebo. Large neutral aminoacids (LNAA) competes with phenylalanine for transport across the blood-brain-barrier and have a beneficial effect on executive functioning. A new therapy has just been approved that can be effective in most patients with PAH deficiency regardless of their degree of enzyme deficiency or the severity of their phenotype. Phenylalanine ammonia lyase (PAL-PEG) was approved in the USA by FDA in May of 2018 for adult patients with uncontrolled blood phenylalanine concentrations on current treatment. Nucleic acid therapy (therapeutic mRNA or gene therapy) is likely to provide longer term solutions with few side effects.

Objectives: This study is a practice based research conducted to investigate the effectiveness and safety of a 5-day short-term diet program ('Oil-rescue' program) designed to reduce the adverse events and initial dropout rate in obesity treatment. Methods: We retrospectively analyzed 4 Korean medicine clinic patient data who completed 'Oil-rescue' program which is consisting of Gambi-hwan, Bium-hwan, Butgiban-hwan and Jayoon Kyungokgo. The weight change before and after participating 'Oil-rescue' program was primary outcome of our study. Changes in body mass index, body fat mass, skeletal muscle mass, body water content, lean body mass, protein, and minerals were also measured. Results: A total of 35 patients who satisfied the eligible criteria were finally included. The body weight decreased from 69.45±11.86 kg to 67.43±11.58 kg, a total of 2.02±1.03 kg (P<0.001). Body fat mass decreased from 25.77±7.45 kg to 24.98±7.26 kg, a total of 0.78±1.21 kg (P<0.001). Body mass index decreased from 26.39±3.64 kg/㎡ to 25.64±3.49 kg/㎡, a total of 0.75±0.41 kg/㎡. (P<0.001). A total of 15 patients had side effects such as diarrhea, abdominal pain, and insomnia, but all were mild. 16 out of 35 people switched to long-term obesity treatment programs. Conclusions: Through this retrospective practice based research, it was found that the 'Oil-rescue' program effectively reduced body weight, body fat, and body mass index, and the other obesity related parameters. It was a relatively safe and effective short-term obesity treatment program.
